The ParseFilterData method unpacks the binary registry data for a filter.
There is typically no reason for an application to call this method. The IFilterMapper2::EnumMatchingFilters method provides a more convenient way to access the filter registry data.
HRESULT ParseFilterData( BYTE *rgbFilterData, ULONG cb, BYTE **prgbRegFilter2 );
[in] Pointer to the binary registry data.
[in] Specifies the size of the binary data, in bytes.
[out] Address of a variable that receives a pointer to the unpacked data. When the method returns, cast this pointer to a REGFILTER2 type to access the filter data. The caller must release the memory by calling the CoTaskMemFree method.
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
Include fil_data.h, which is located in the Mapper Sample directory.
